Ruby Bay grows in 5 turns so I guess we chop the gem hill. Question: What is best way to build the Hanging Gardens in Ruby Bay?
As I wrote in a cross-edit, we won't make it to Size 3 before Mathematics, so there's no need to complete the Chop on the second Gems square until after we learn Mathematics, but we should aim to get the Chop on T97, since the Food box will be about half full at Size 2 at that point.
I suppose that the ideal case would be to whip 60 Hammers into the Aqueduct, even though that would mean not working the 2nd Gems Mine for a couple of turns--we really should put a lot of effort into completing The Hanging Gardens before Hatty or possibly another AI completes it. With 32 H on T97, then another 3 H per turn on T98, T99, and T100, with at least one Chop coming in on T97, we'd have 2 + 3 + 3 + 3 = 11 H plus a Granary.
One more Chop gives us 41 H, which is enough to be able to 2-pop-whip the Aqueduct, but we're another 5 turns from being able to 2-pop-whip. So, let's just plan to 1-pop-whip the Aqueduct.
So, assuming that we don't mind delaying when we work the second Gems Mine, we don't even need to Road and Mine it for a long time, as we could aim to 1-pop-whip on T99 when we're about to grow to Size 3.
To make that happen, we'd need 3 Chops to arrive on T97 or T98.
We'd then have something like 2 base Hammers in The Hanging Gardens on T100.
As of T100, we would then want another 5 Forest Chops as soon as possible.
So, I would say that there is no time for Roads, no time for Mining the second Gems square, and after all 3 Workers Mine the first Gems square, we just prepare to pre-Chop before T97 and then Chop till we drop from T97 onward.
We have 7 Chops available to us and I said that we need 8 Chops. So, maybe it would still help to Mine the second Gems square. Or, we might end up whipping The Hanging Gardens. Let's see... with 2 H on T100, and earning 3 H per turn, it would take us another 15 turns to manually earn the Hammers, which is way too long. Even with a few extra Hammers from working the second Gems Mine, we'd earn Hammers too slowly. Thus, it will probably be whipping out the last bit of The Hanging Gardens, not Mining the second Gems square, and just Chopping as much as we can as quickly as we can.
Ruby Bay should "enable" the Forest that is 1 N of York to go into Ruby Bay (click on that Forest in Ruby Bay's City screen to enable it for Ruby Bay's usage and therefore Ruby Bay would get the Chop instead of York).
If we happen to gift Churchill a new City (Vlad?) and manage to raze Nottingham, we'd have a Forest for our 8th Chop, otherwise we could just Whip out the last bit of The Hanging Gardens.
With all 3 Workers completing the Gems Mine on T90, that leaves them doing:
T91 Move to a Forest
T92 Pre-Chop
T93 Pre-Chop and STOP
T94 Move to another Forest
T95 Pre-Chop
T96 Pre-Chop and STOP
T97 Wait for Mathematics to come in and then complete the Chop... but, not all 3 Workers can do so, otherwise we'd get too many overflow Hammers, so we could say that one Worker could be on the second Gems square and could put a turn into Roading it.
Doing so gives us our Granary and 30 H Chopped into the Aqueduct, and another 30 H Chopped into the Aqueduct on T98, but then we'd just have 68 H in the Aqueduct, which would not be enough to make it a 1-pop-whipping action.
So, one of the Workers could move to the Forest that it Pre-Chopped on T98, Chop it on T99, but that Chop would come at a bad time, as we'd Chop on the turn where we earned 3 more H, giving us 68 + 30 from Chop + 3 = 101 H to complete the Aqueduct, but we wanted to 1-pop-whip it. So, neither Worker would move to its Pre-Chopped Forest on T98 and those two Workers could both move to the 7th Forest on T98. They both Chop it on T99, then on T100 when we whip the Aqueduct (I think that the City will have just grown to Size 3), one of those Workers can finish the 7th Chop while the other Worker moves to its Pre-Chopped Forest.
Meanwhile, the Worker who was on the Gems square Roaded on T97, Chopped on T98, complete the Road on T99, then moves to the Pre-Chopped Forest that one of the other two Workers Pre-Chopped, giving us our 6th and 7th Chops coming in on T101, allowing us to whip the rest of The Hanging Gardens on T102.
Except that I said all of that within a "vacuum," without considering that there isn't a Forest adjacent to the second Gems square. So, we'd need a Worker to arrive on the second Gems square as its final Chopping location, having arrived there via a Road built, say, at 1 SE of Ruby Bay.
Also, there's a bit of a problem since the Forests at SE + S of Ruby Bay and SE + E of Ruby Bay won't be in our Cultural Borders until T101, so we can't Chop them until that Turn, so those Forests would be ones that we Pre-Chop early on. Yet, the Forest at SE + S takes 2 turns to get to.
So, we should have two Workers who Chop the fastest end up being adjacent to each other to be able to build a Road at 1 S of Ruby Bay, to improve Worker logistics.
Anyway, let's just write it out to see how it might work...
So, something like:
T90 All 3 Workers Mine the first (1 E of Ruby Bay) Gems Mine
T91 W4 to G For at 1 S of Ruby Bay, W5 to GH Riv For at 1 SE + 1 E of Ruby Bay, W6 to G For at 1 SW of Ruby Bay
T92 W4 moves 1 SE G For (1 SE + 1 S of Ruby bay and 1 N of the Horse), W5 and W6 Pre-Chop
T93 W4 Pre-Chops, W5 and W6 Pre-Chop and STOP
T94 W4 Pre-Chops and STOPs, W5 moves 1 W G Riv For (1 SE of Ruby Bay, 2 N of the Horse), W6 moves 1 E G For (1 S of Ruby Bay)
At this point, we have these 3 Forests Pre-Chopped:
G For at SE + S of Ruby Bay (1 N of the Horse)
GH Riv For at SE + E of Ruby Bay (1 N of the Fur)
G For at 1 SW of Ruby Bay (1 S of the Fish)
T95 W4 moves 2 W G For (1 N of York), W5 Pre-Chops G For at 1 SE of Ruby Bay, W6 Pre-Chops G For at 1 S of Ruby Bay
T96 W4 Pre Chops G For (1 N of York), W5 Pre-Chops G For at 1 SE of Ruby Bay and STOPS, W6 Pre-Chops G For at 1 S of Ruby Bay and STOPS
T97 Wait for Mathematics to come in
T97 W4 Pre-Chops G For at 1 N of York, W5 finishes Chop at 1 SE of Ruby Bay, W6 finishes Chop at 1 S of Ruby Bay
T98 W4 finishes Chop at 1 N of York, W5 moves 1 W to G at 1 S of Ruby Bay and builds a Road, W6 (at 1 S of Ruby Bay) completes the Road
We now have Chopped these Forests:
1 SE of Ruby Bay (2 N of the Horse)
1 S of Ruby Bay
1 SW + 1 S of Ruby Bay (1 N of York)
T99 W4 moves 1 N to G For at 1 SW of Ruby Bay, W5 and W6 move along the Road to the second Gems square
T100 W4 completes the Chop at 1 SW of Ruby Bay, W5 and W6 each put a Chop into the second Gems square...
it's not working out very well.
Okay, the solution probably does involve Roading the second Gems square, then moving away from there, such that we only end up with 1 Road built, but building that Road saves us a Worker turn later.
Anyway, back to the drawing board, but the basic ideas are there.
